Embodiment Construction

[0044] see figure 1 , the structural form of the integrated cable for sea islands in this embodiment is: two coaxial cables 1, two pairs of twisted cores 2, three power cable insulated cores 3 and waterproof filling rope 4 are jointly twisted to form a cable core; The exterior of the cable core is sequentially provided with an extruded inner sheath layer 5, an armor layer 6 made of aluminum alloy wires, and an outer sheath layer 7 formed of extruded polyethylene. The twisted pitch diameter ratios of the two sets of twisted core wires 2 are different. The two coaxial cables 1 and one pair of twisted core wires 2 are located in the outer gap of the three power cable insulated cores 3, and the other pair twisted The core wire 2 is located in the center of the three insulated wire cores 3 of the power cables.

[0045] Such as figure 1 and figure 2 As shown, the coaxial cable 1 is centered on the coaxial cable copper core conductor 11, and the coaxial cable insulation layer 12,...

Abstract

The invention discloses a comprehensive cable for a sea island and a fabrication method of the comprehensive cable. The comprehensive cable is characterized in that a cable core is formed by jointly twisting two coaxial cables, two groups of twisted-pair wire cores, three power cable insulation wire cores and a waterproof filling rope, and an inner sheath layer formed through extrusion, an armor layer formed by spare winding of an aluminum alloy wire and an outer sheath layer formed through extrusion by taking polyethylene as a material are sequentially arranged outside the cable core from inside to outside. In the comprehensive cable for the sea island, a power wire core and a communication and data transmission cable are integrated; and compared with a dispersed cable, the comprehensive cable has the advantages that the manufacture and laying cost of a product are greatly reduced, meanwhile, the maintenance cost of the cable is also reduced, and the comprehensive cable has obvious economic benefit.

Description

technical field [0001] The invention relates to an electrical equipment instrument cable and a preparation process thereof, in particular to an integrated cable for sea islands and a manufacturing method thereof, belonging to the technical field of electric wires and cables. Background technique [0002] my country is a large oceanic country with a sea area of ​​more than 3 million square kilometers and a coastline of 18,000 kilometers. There are more than 6,000 islands along the coast. There are rich submarine oil fields and natural gas in the shallow sea continental shelf. The coast is also an economically developed area in my country. The development of coastal islands urgently needs electricity. Due to the high cost and long period of construction of power stations, and the difficulty of fuel supply, etc., power supply and communication (especially military confidential communication) for small and medium-sized islands need to pass through long-length photoelectric integra...
